About car suspension, a comprehensive understanding of car suspension knowledge will make you an old driver. Friends often say that it is really difficult for your car to absorb shock, or that the chassis of this car is not solid enough to drive. In fact, these driving experiences have a lot to do with the suspension of the car. Today, let's talk about various pauses.

What exactly is suspension? Simply put, automobile suspension system refers to the whole support system composed of springs and shock absorbers connected to tires. The correct function of suspension system is to support the car body to improve the riding experience. Different suspension settings will make evil have different driving feelings.

Many friends will find McPherson, torsion beam, multi-link and so on when choosing a car. According to the different structures, these suspension forms can be divided into two categories: independent suspension and dependent suspension. Each wheel of an independent suspension car has its own damping structure. Figuratively speaking, the wheels are busy, but they are actually two wheels on a shaft, which are connected by an integral frame.

Here are several common suspension forms on the market. McPherson suspension is the most common independent suspension, which is generally used in the front suspension of automobiles. The main structure is composed of spiral spring, shock absorber and A-shaped lower arm. The shock absorber can avoid the phenomenon that the spiral spring deviates to the front, back, left and right when stressed, and limit the spring to vibrate only in the up and down direction;

Moreover, the performance of suspension can be adjusted by adjusting the stroke and damping of shock absorber and cooperating with spiral springs with different hardness. McPherson suspension has the advantages of small volume and simple structure, which is conducive to a more compact engine compartment layout. But it is precisely because of the simple structure and insufficient lateral support that steering tilt and braking nod are more obvious!

Torsion beam suspension is a kind of automobile dependent suspension, which is generally used for rear suspension. Its working principle is that the wheels of non-independent suspension are installed at both ends of a torsion beam. When one wheel jumps up and down, it will drive the other wheel to jump accordingly, reducing the inclination or swing of the whole car body. Its principle is similar to the seesaw played when I was a child. Many models will add an extra balance bar to this suspension to tilt the wheels, thus achieving the purpose of vehicle stability.

Finally, let me talk about the air suspension that many high-end luxury cars are equipped with. Compared with other independent suspensions, air suspension uses air pump to adjust the air volume and air pressure of air shock absorber, thus changing the hardness and elastic coefficient of air shock absorber. Similar to the pump, it is more used in the chassis lifting system to raise or lower the chassis, so that the vehicle has both the comfort of the car and the passability of the off-road vehicle.

To sum up, the main task of suspension is to transfer the force between the wheel and the car body and reduce the impact of the road surface on the car body. Therefore, the comfort of a car is largely determined by the suspension, and the quality of suspension adjustment is also an important indicator to test the assembly level of major manufacturers. Whether a car has a sense of driving ahead is inseparable from suspension training. More vividly, the suspension of a car is like a human knee. If you want to be comfortable or exercise, you must
